Guhring 9065090051600 Extra Length Carbide Drill Bit

Product Description

The GUHRING 9065090051600 is a solid carbide extra length drill bit engineered for deep hole drilling applications in demanding production environments. Part of the Series 6509 RT100 T platform, it features a TiAlN coating that extends tool life in high-temperature cutting conditions. The 0.203 inch diameter bit carries a 135-degree point angle with web thinning for accurate self-starting entry. With a flute length of 110 millimeters and an overall length of 150 millimeters, it achieves a 15xD depth-to-diameter ratio. The h7 shank diameter tolerance ensures consistent fitment in precision toolholders. This bit is installed and operated by machinists and CNC programmers in metalworking shops.

This drill bit is designed for deep hole drilling in cast iron, stainless steel, and steel as primary workpiece materials, with aluminum and titanium alloy as secondary workpiece materials. The spiral flute geometry with a regular spiral type promotes effective chip evacuation during extended-depth cuts. The straight-cylindrical shank with a 6 millimeter shank diameter and 36 millimeter shank length suits standard collet chucks and drill holders. Coolant-through capability supports through-tool coolant delivery, which is critical for maintaining tool life and chip control at depth. Right-hand cutting direction is standard for conventional spindle operation.

Key Features

• Solid carbide construction with TiAlN coating for high-heat resistance and extended tool life
• 135-degree point angle with web thinning for accurate, low-thrust entry
• Coolant-through design supports internal coolant delivery for deep hole chip management
• 15xD flute-to-diameter ratio enables drilling depths up to 4.026 inches (102.26 millimeters)
• h7 diameter tolerance ensures precise fitment in collet chucks and precision toolholders
• RT100 T point type optimized for cast iron, stainless steel, and steel workpieces

Compatibility

Rated for primary workpiece materials including cast iron, stainless steel, and steel (ISO material codes K, M, P) and secondary workpiece materials including aluminum and titanium alloy (ISO codes N, S). Designed for use in CNC machining centers and drill presses equipped with through-tool coolant capability and collet or hydraulic toolholders accepting a 6 millimeter straight-cylindrical shank.

Installation Notes

Installation and setup should be performed by qualified machinists following the machine tool manufacturer guidelines. Secure the shank fully in a collet chuck or hydraulic holder and verify runout before beginning a cut. Disengage spindle power and confirm the machine is in a safe state before changing or inspecting the bit. Do not exceed the rated maximum drilling depth of 4.026 inches without confirming workpiece and fixture rigidity.
